auto-save-name: preference variable

Default value: "%p#%b%e.asv#"

When want-auto-save is nonzero, Epsilon regularly saves a copy of
each unsaved file. This variable contains a template which determines
how Epsilon chooses the file name for the autosaved file. Epsilon
substitutes pieces of the original file name for codes in the
template, as follows (examples are for the file c:\dos\read.me):

%p

The original file's path (c:\dos\).

%b

The base part of the original file name (read).

%e

The extension of the original file name (.me).

%f

The full name of the original file (c:\dos\read.me).

%r

The name of the file relative to the current directory.
(read.me if the current directory is c:\dos, dos\read.me if the
current directory is c:\, otherwise c:\dos\read.me).

%x

The full pathname of the directory containing the Epsilon
executable.

%X

The full pathname of the directory containing the Epsilon
executable, after converting all Windows long file names to their
equivalent short name aliases.

By default, Epsilon writes to a file in the same directory but with a
# character before the name and .asv# after it. If you change
this to %f (to auto-save to the original file name) or some other
setting that could name a file you want to keep, be sure to set
appropriate bits in the want-auto-save variable to
disable automatic deletion of auto-save files.
